CVE-2022-47951Public exploitNetwork attack vector

Server file disclosure via crafted VMDK descriptor

Published Jan 26, 2023 · Updated Mar 31, 2025

Path traversal in OpenStack Cinder, Glance, and Nova allows remote authenticated users to read server files through a crafted VMDK image. VMDK processing accepts a flat descriptor whose extent path names an arbitrary backing file, then returns the referenced file's contents. A valid project account and subsequent image processing are required; Glance is affected only when image conversion is enabled.
